Not Nvidia. Not TSMC. This Equipment Maker Is the Real Bottleneck in AI Chip Production.

Nvidia and TSMC are often viewed as the main AI-chip players, but an article argues the true constraint is ASML, the Netherlands-based supplier of lithography equipment. ASML makes the systems used by foundries—such as TSMC, Samsung and Intel—to etch circuit patterns onto silicon wafers, including EUV tools used for the smallest, densest chips. The piece notes ASML’s EUV systems, the only high-end option, cost roughly $200 million to $400 million and require onsite assembly, leaving few direct competitors. As AI chip demand rises, ASML’s EUV revenue has overtaken DUV over the past three years; for 2026 it expects revenue growth of 35%–38% and a 56% gross margin.
